These are the 10 most polluted places in Yorkshire

Environmental charity Friends of the Earth have released a list of the 10 most polluted Yorkshire locations.

The data has been compiled by measuring levels of the pollutant gas nitrogen dioxide in each spot. The Neville Street tunnel in Leeds, which is Yorkshire's pollution hotspot, is also the most toxic place in the UK outside of London.
